Both Windows and macOS have several internal tools to monitor the activity of computer components such as memory usage, network, and percentage of the processor. However, temperature is not one of the data that we will find there.
Neither the Task Manager nor the Windows Resource Monitor, nor the Activity Monitor in macOS, show data like the temperature of our CPU. However, we have options: use a third-party tool or check from the BIOS.
The second option loses a bit or all the sense if we want to monitor the temperatures while using the computer, since obviously you have to restart, go to the BIOS and look for the temperature information that varies in how and where it is shown depending on your motherboard.
Tools to monitor the temperature in Windows 10
In Windows we have two very good and free options, almost indistinguishable from one another: HWMonitor and Open Hardware Monitor, the second is open source but it is updated less frequently. Both do exactly the same and have basically the same options.
HWMonitor you have to install it, while Open Hardware Monitor is portable and just run the .exe inside the program’s file folder. The choice is yours.
In both you will find the list of all your components, the temperature of each one (CPU, GPU, Plate, Discs), their voltages, even your fans and the speeds at which they are rotating.
Of course, if you want to go a little beyond just see the information, Open Hardware Monitor offers additional things, such as the option to keep records every so often, while HWMonitor only lets you save the immediate record at that time.
Tools to monitor the temperature in macOS
For macOS we are also going to recommend two options, these are quite different. The first is Intel Power Gadget and is compatible with Intel Core processors from second through seventh generation. It is extremely simple, and only shows you the current temperature of the package.
The second is iStats Menus, and this one does have extremely detailed information about the different temperatures of the components of your computer. The only bad news is that it is paid, although you can use it for free for 14 days of testing.
You just have to make sure to activate the “Sensor” from the options so that in your menu bar appears a small icon that says “SEN” with the letters in vertical. Click on it, it shows you all the temperatures in detail.
You can choose what you want to show and not directly from there.
